Abstract

PURPOSE: To enable the presence or absence and the position of a failured fuel pin to be detectable at the same time, and to promote the efficiency of inspection, by means of arranging sound detectors around the fuel assembly, and of detecting the sound of liquid ejected from the failured fuel pin by the change of pressure within the vessel of inspection.
CONSTITUTION: A fuel assembly P is planted in the vessel of inspection 1, and a prescribed quantity of a liquid Q is introduced to the vessel 1, and then when the pressure in the vessel 1 is allowed to be raised by introducing high pressure, the liquid is entered in the fuel pin. When the pressure is lowered by means of discharging the gas in the vessel 1 after a prescribed time, the liquid Q impregnated in the fuel pin is ejected out of the pin, and the sound is generated. This sound is detected by sound detectors 18a, 18b, 18c, 18d installed around the fuel assembly P, and its signal is entered to an operating circuit 25 from a controller 17, and from the timely difference of output signal thereof, the position of sound generation is calculated and indicated by an indicator 26
